摘要

This review systematically summarizes the latest advances in polymer processing techniques for thermoelectric applications and explores the intrinsic relationships among the processing methods

microstructure

and thermoelectric performance. Finally

future perspectives are presented for the industrialization of high-performance organic thermoelectric devices.

Abstract

Thermoelectric (TE) materials

which are capable of direct conversion between heat and electricity

offer a promising solution for sustainable energy harvesting. Conjugated polymers have emerged as compelling candidates for flexible TE devices owing to their intrinsic flexibility

low cost

and low thermal conductivity. The performance of polymer-based organic thermoelectrics (OTEs) is profoundly influenced by the processing methods

which dictate molecular packing

crystallinity

and film morphology. This review systematically summarizes recent advances in polymer processing techniques for TE applications

including solution processing

patterning techniques

and large-area fabrication. We discuss the interrelationships among processing techniques

polymer microstructure

and TE performance

concluding with the current challenges and future perspectives for industrializing high-performance OTE devices.
